_Aboriginal Chambers near Tilbury._--It is proposed to descend some of
the aboriginal chambers alluded to by Camden, near Tilbury in Essex. In
consequence, however, of Camden having named a wrong parish, later
antiquaries have been puzzled to ascertain their precise whereabouts.
Mr. Crafter, in 1848, after many days' labour, found them out; and a
brief notice of them was given {463} in an article upon "Primæval
Britain" in the _West Kent Almanack for_ 1849. Hasted mentions similar
pits in Crayford Parish, Kent. In Dartford parish is another called "the
Sound Hole," from the echoes, &c., made upon a stone being thrown down.
Mr. S. Laudale intends an examination of it this summer. Tradition
reports that there are three enormous caverns, which communicate with
the central shaft.
How, or what, is the best way of driving the foul air out of those
chambers which are aloof from the central shaft?

_Sir R. Haigh's Letter-Book._--A few days ago, Messrs. Puttick and
Simpson sold a very important manuscript, the original letter-book of
Sir R. Haigh, of Lancashire, of the time of Charles II. It fetched 51l.,
being bought by a collector whose name has not transpired; but perhaps
this notice, if you kindly insert it, may induce the purchaser to edit
it for the Chetham Society, to whose publications it would for a most
valuable addition.
